Specification of Letters Patent.

Patented A11 10, 1915.

Original application filed January 31, 1914, Serial No. 815,688. Divided and this application filed July 11,

To alt whom it may concern I Be it known that we, HENRY JosHUA PHILLIPS and ARTHUR PHILLIPS, subjects of the King of England, residing at Lon don, in England, and Monmouth county,

verge and meet at the edges situated at the interior of the mold.

Other features of the invention relate to the construction of presswplungers and to the arrangement of the constructional details of the press.

For a more complete. understanding of the invention reference is directed to the accompanying drawings wherein a particular construction of press is illustrated for compressing the wetpulpfrom which coal briquets are made. I

The invention will be described in. connection with the process for the manufacr ture of coal briquets described in the specification of our application for Letters Patent Serial No. 815688, from which the pres ent application has been divided. This mode of description has merely been adopted for the sake of convenience, since it is to be understood that the press according to the present invention may be applied to many uses other than the manufacture of coal briquets.

1914. Serial No. 850,414.

small coal is ground in water to a pulp and the aqueous pulp thus produced is fed clirectly, i. eswithout being left to settle, into a press which constitutes the subject matter of the'present application and in which the pulp is compressed to eliminate a large proportion of the water and consolidate it into briquet form. Three to five tons per square inch will be found to be a convenient pressure, and this will produce cohesive briquets.

The press shown in the drawings com prises an outer casing A of rectangular section. This section is preferred since the briquets produced are more easily packed or stored than if, say, a circular section were adopted. The casing A is lined on the interior with a series of vertical bars which are secured to the casing by bolts passed through flanges B on the bars and flanges A on the casing. The flanges A on the casing have grooves sunk therein to receive the flanges B so that the end surfaces of the mold may be unbroken. The projections A between said grooves come flush with the surface of the flanges B The adjacent side faces of thebars, i. e. the faces B B converge and meet at the edges B siutated at the interior of the mold. Thus at the interior the bars form a mold having practically continuous surfaces, but at the back of each of these surfaces there runs a series of vertical through-ways of V-section which can convey away any liquid forced out of the pulp and between the bars. At the corners of the casing A filling bars B are provided to operate in conjunction with the bars B. To permit the filling bars B to be placed in position, one or both of the projections A adjacent each bar 13 may be detachable.

Mounted to reciprocate within the mold there are shown two oppositely-acting plungers O, D which are fluted on their vertical faces at C and D respectively and on their end faces at C and-D respectively. The plungers are also each provided on their end faces with a series of bars C and D These bars run transversely of the flutes C and D in the end faces of theplungers, and the bars are secured to the plungers by screws C and D The adjacent side faces of the'bars C and D converge in a similar manner to the faces B and B of the bars.

13, and meet at the edges C and D which are situated at the interior of the mold. It is thus provided that liquid pressed out of the pulp may readily drain away from the faces of the plungers through the flutes and throughways provided. Conveniently the, bars B, B C and D are of some non-rusting metal, such as phosphor-bronze.

Any suitable means (not shown) may be employed for reciprocating the plungers, and for feeding the pulp to the interior of the mold.

The blocks or briquets made in the press above described can be placed on trolleys or endless belts or the like for transportation to a heating tunnel or other apparatus, or to a store-house, and may be subjected to any desired subsequent heating and com pressing.

It will be appreciated that the press according to the present invention is specially adapted for permitting fluid, contained in the pulp being compressed, to drain away readily when pressure is applied to the pulp by means of the plungers. Thus when it is used in the process of the aforesaid application Serial No. 815688 the necessity for allowing the pulp or sludge to settle and a certain proportion of the water to drain away, is obviated. An operation is thus eliminated which is rather lengthy and which gives rise moreover to stratification of the pulp.

As already stated, the press may be put to other uses than that herein described, since any pulp or liquid-containing substance may have moisture or liquid extracted from it in the press.

It will be appreciated that different classes of materials require different degrees of pressure which can readily be found by experiment.

The invention is not limited to the employment of the precise construction of press hereinbefore described. This will give good results, but it may be modified in certain details without departing from the spirit and scope of the invention as defined by the appended claiming clauses.

What we claim as our invention and desire to secure by Letters Patent is 1. A press having a mold-lining comprising a series of vertical bars whereof the adjacent side faces converge and meet at the edges situated at the interior of the mold, said bars having flanged ends for securing the bars in position, for the purpose described.

2. A press having a mold-lining of rectangular cross-section comprising a series of vertical bars whereof the acent side faces converge and meet at the edges: situated at the interior of the mold, said bars, having flanged ends for securing the bars in position, for the purpose described.

3. A press comprising a mold, in combination with a plunger to reciprocate in the mold, and fluted on its side faces, and on its end face, and provided on its end face with a series of bars which run transversely of the flutes in the said end face, the adjacent side faces of said bars converging and meeting at the edgessituated at the interior of the mold, for the purpose described.

4:. A press comprising a mold of rectangular cross-section, in combination with a plunger, also of rectangular cross-section, to reciprocate in the mold and fluted on its side faces and on its end face, and provided on its end face with a series of bars which run transversely of the flutes in the said end face, the adjacent side faces of the bars converging and meeting at the edges situated at the interior of the mold, for the purpose described.

5. A press comprising the CODLulllELtlOll of a mold lining consisting of a series of vertical bars whereof the adjacent side. faces converge and meet at the edges situated at the interior of the mold, and two oppositelyacting plungers to reciprocate in the mold, each of said plungers being fluted on its side faces and on its end face, and being provided on its end face with a series of bars which run transversely of the flutes in the said end face, the adjacent side faces of the bars. converging and meeting at the edges situated at the interior of the mold, for the purpose described.

6. A press comprising in combination a flanged casing of rectangular cross-section, having a lining. in its interior consisting of a series of vertical bars having flanges corresponding with the flanges on the casing, the adjacent side faces of said bars converging and meeting at the edges situated at the interior of the mold, means passing through the flanges for securing the bars in position in the'casing, and oppositely-acting plungers to. reciprocate in said mold, each of said plu-ngers being fluted on its vertical faces and on its end face, and being provided on its end face with a series of bars which run transversely of the flutes in the said end face, the adjacent side faces of the bars converging and meeting at the edges situated at the interior of the mold, for the purposes described.
